Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus are described for operating a high voltage d.c. (HVDC) transmission line system connecting two a.c. transmission line systems during normal operation and during malfunction in either the rectifier station or the inverter station of the HVDC system.  When a malfunction exists in one station of a HVDC transmission line (e.g.,rectifier station A), then the regular thyristor firings are disabled and a bypass circuit, preferably one or several bridge paths of a converter, are fired.  As soon as a corresponding change in the current or voltage occurs at the d.c. voltage connections of the other station (B), this station assumes rectifier operation during which the HVDC transmission line is utilized as a reactive load to stabilize the other system.  Once the malfunction has ceased to exist, operation is first resumed in station A by extinguishing the bypass thyristors and subsequently resumed also in station B.  This procedure permits stable normal operation in both stations, or bypass operation without using remote control signals during which the HVDC transmission line can be rapidly controlled to stabilize the systems.

Abstract: NMR GRADIENT FIELD MODULATION                       ABSTRACT         A circuit and method are disclosed for providing high, constant amplitude sinusoidally modulated NMR gradi-ent fields.  A capacitor is connected in parallel with the gradient coil, but separated by a switch.  A pre-determined amount of energy is stored in the capacitor and then the switch is closed to permit a sinusoidal oscillation of energy between the capacitor and gradient coil.  By pre-charging appropriately, sine wave or cosine wave oscilla-tion can be obtained for the NMR system.  The oscillation is terminated by opening the switch at a time when all of the oscillating energy is in the capacitor.  In a preferred embodiment of the invention, the switch is a bridge cir-cuit, each of whose sides is a back-to-back thyristor pair, so that the gradient field may be modulated either as a full wave, half-wave rectified or non-rectified sinusoidal oscillation.  In one embodiment, a full-wave rectified sine wave is used, and all the oscillating energy is caught in the capacitor during intervals in which 180° RF pulses are applied to generate echoes. Image data is collected during the sinusoidal oscillation.

Abstract: HOT AIR SCREENING AND TRANSPORTING SYSTEM     Max Krell Rock Forest, Que., Canada Abstract The disclosure herein describes a system which allows to screen efficiently and safely the heat of a heat produc-ing system, most probably a wood stove.  This way the sur-rounding space can be kept reasonably temperate and the excess heat will be transported to other places, like it is the case in central heating systems.  The special new feature of this system is a gravity operated flap which prevents hot air from being stalled in the case of a power failure.  This is an essential safety device for all types of combustion processes which do not automatically stop in the case of a breakage of the cooling cycle.

Abstract: COMPLETION FOR TAR SAND SUBSTRATE                  ABSTRACT OF THE DISCLOSURE           Method and apparatus for recovering hydrocarbons from a subterranean formation in which a well completion, including a well liner, lies in a generally horizontal disposition within the hydrocarbon productive substrate.  The liner encloses conductor means for delivering a stream of a hot stimulating agent to the well's remote or injection end, and means for regulating the production of bitumen emulsion from the producing end thereof.  A fluid impervious barrier it movably interposed in the well liner between the injection end and the producing end to establish a pressure differential across said barrier thereby directing a flow of stimulating agent into the substrate.  Said agent, by liquefying bitumen, creates a pattern of paths along which the mixture flows toward the well's lower pressure producing end.  By progressively moving the barrier toward said producing end, the flow path pattern can be extended into a broader area of the substrate.

Abstract: Abstract A process for producing an indole which comprises reacting an aniline and a diol in the presence of a catalyst to produce a reaction mixture containing the indole, unreacted aniline and by-products, condensing the reaction mixture to obtain a liquid reaction product, recovering the unreacted aniline from the liquid reaction product, reducing the contents of specified by-products in the recovered aniline below specified levels and reutilizing the resulting recovered aniline.  To reduce the contents of the specified by-products, in the recovered aniline below  specified levels,  it is preferred to subject the liquid reaction product or an aniline fraction separated therefrom to a heat-treatment and then to distillation.   In the above manner, the  recovered aniline can be reutilized in the reaction without causing the activity of the catalyst to deteriorate.

Abstract: CRYSTALLINE GALLOPHOSPHATE COMPOSITIONS                 ABSTRACT OF THE DISCLOSURE        A novel family of crystalline, microporous gallophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures from gallophosphate gels containing a molecular structure-forming template. The family comprises distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter.  The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.
